針對(duì)柔性化制造的要求，構(gòu)建了以DSP＋CPLD為基礎(chǔ)的數(shù)控系統(tǒng)平臺(tái)。該平臺(tái)集成度高、穩(wěn)定性強(qiáng)，能實(shí)現(xiàn)生產(chǎn)過(guò)程的高速度、高精度要求，實(shí)現(xiàn)了基于CPLD的可重構(gòu)設(shè)
計(jì)，提高了系統(tǒng)的柔性。在控制算法上,采用單神經(jīng)元PID 及CMAC 相結(jié)合的伺服運(yùn)動(dòng)控制算法，仿真顯示較常規(guī)PID控制有更好的動(dòng)態(tài)特性、控制精度、抗干擾能力。

Abstract: A hardware development platform for the computer numerical control system was built based on the DSP+CPLD. It is characterized by the high integrity and robust stability, meets the requirements of the production process on high speed and high precision. the reconstructable design based on the FPGA was realized to enhance the flexibility of the system, For the control algorithm ,which combines single neuron PID with CMAC to control system is used , Indication through the simulation shows that the control algorithm has better dynamic performance、control precision and strong capability of anti-jamming compared to the traditional PID.
